SPECIEFICATION forming part of Letters Patent No. 783.740, dated February 28, 1905.

Application filed October 7,1904. Serial NoV 227,541.

To (all wltoln/ t n1/(ty concern:

lie it known that I, FRIED BAKKER, a citizen of the United States, residing in Paterson, in

the county of Passaic and State oi" New Jersey, have invented certain new and useful Improvements in Inlet Structures for (latch-Basins; and l do hereby declare the following' to be a lull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters oli reference marked thereon, which form a part ot' this specilication.

The invention relates to inlet structures for catch-basins or cesspools whose receiving openings or mouths are arranged in the gutters of streets having curbing; and it conteur plates certain improvements hereinafter set llorth having for their principal object to make such structures adjustable to various heights ot' curbing.

To this end my invention consists in a catchbasin-inlet structure comprising two separate parts, one of which rests flush with the gutter-surface and the other of which stands in a break or recess in the curb Hush with both the topand vertical faces thereof, so arranged and constructedas to resist displacement from ordinary causes after installation and yet be susceptible of adjustment during installation, particularly to suit various heights of curbing'.`

ll have fully illustrated my invention in the accompanying' drawings, wherein-- Figure l is a view showing a catch-basin in section and my improved inlet structure in side elevation. Fig. 2 is a view showing the improved inlet structure in front elevation. Fig. 3 is a view, partly in plan and partly `in horizontal section, on the line a' .fr in Fig. 2 of said inlet structure, showing one form oi grating or strainer. Fig. 4 a sectional view on the line y in Fig. 3; and Fig. 5 is a view ot' the improved inlet structure in vertical section, showing a part ot the farther side of the strainer or grating supporting irame broken away and also showing a modified i'orm ol strainer or grating.

a in the drawings is a catch-basin, and 7) its outlet-pipe.

` c indicates the street-surface, and the curb, the latter having a break or recess therein, as at e.

f is a three-walled rectangularbody having' formed about its base a supporting-llange y, whereby it is sustained on the brink or sill ot' the catch-basin, with its top [lush with the street or gutter surface and its open side toward the curb. is another rectaligular body which is .set in theI curb, with its top and lront faces i'lush with the correspond ing 'faces of the curb. The bottom side of this body is removed, Vforming an opening i, and its front side is provided with another opening/, which receives the open side ot the body j", as best seen in Fig. 3. The part f lits snugly into the openingy in the part t, and thus lateral play of either part on the other prevented. Part f is provided adjacent the part 71. with two alined outwardly-extending lugs or guides and these are received b v two corresponding opposed grooved guideways arranged vertically on the front of the part /a This arrangement permits vertical movement ot the parts f and /t the one on the other, but prohibits all other play.

I provide a supporting attachment for the part t, whereby the latter may be sustained at any desired height, according' to the height oi the curb. This is in the form of a plate m, having' a base or flange n, which rests on the brink or sill oi' the catch-basin. The plate is vertically slotted, as at o, and it receives in said slots bolts 7), which may be carried by the part L, or the bolts may be mounted in the plate and the slots be `lornied in the part /l, as will be obvious. This supporting attachment maybe placed either outside oi' the part L, as shown in Fig. l, or ou the inside, as in Fig. 5. li' inside, the top surface otl its base a should be beveled oii, as at q, for drainage.

fr is the grating' or strainer. This seats in a recess s, Yformed in the top of the pai-tf. ln order to prevent unduly-large bodies linding their way into the catch-basin at the back of the strainer, the bars zi' of thelattcr may be extended back into the part ot' the inlet structure, as shown in Figs. 3 and el at a, or vertical bars n may be formed at the back ol the strainer to :uriproximately the height ol .TOO

the opening j in part 7L. In Fig. 3 the two endmost bars u are shown as each carrying' two other bars fw, disposed at right angles thereto and partially closing off the opening that would otherwise he left at this point at the two ends of the part L.

Constructed asabove described the inlet structure can be made to adapt itself to various heights of curbs by tirst settingI in place the body f, then the body 7L, with the latters supporting attachment resting on the catchbasin sill, and then adjusting the height ofthe body /z to suit the elevation of the curb by manipulating' the bolts p.

Having thus fully described my invention, what I claim as new, an l desire to secure b Letters Patent, is-

1. In a catch-basin inlet structure, the combination of two supporting parts adapted to be themselves supported independently of each other, and one ot them constituting a hollow horizontally-arranged grating-supporting part, and a third vertically-arranged hollow part open on the side toward said other hollow part and also at the bottom and adjustably sustained by said supporting parts, substantially as described.

2. In a catch-basin inlet structure, the combination of two supporting parts adapted to be themselves supported independently ot' each other, and one of them constituting` a hollow horizontally-arranged grating-supperting part, and a third vertically-arranged hollow part open on the side toward said other hollow part and also at the bottom and guided for vertical adjustment in said other hollow part, and means for adjustably securing said third part to the other supporting part, substantially as described.

3. In a catch-basin inlet structure, the combination of two supporting parts adapted to be themselves supported independently of eachother, and one of them constituting a hollow horizontally-arranged gratingsupporting part, and a third, vertically-arranged, hollow part` open on the side toward said other hollow part and also at the bottom, said gratingsupporting part and the third part having the Y one guides and the other vertical guideways receiving said guides, and means for adjustably securing said third part to the other supporting part, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 5th day ot' October, 1904.

FRED BAKKER.
